The Rockies' offense just took a hit. Troy Tulowitzki broke his wrist after getting hit by a pitch on Thursday afternoon, an injury that wasn't revealed until the Rockies returned to Denver today, per Tracy Ringolsby.

Obviously, this is bad news for the Rockies: Tulowitzki was hitting .306/.375/.502 with nine homers and 34 RBI on the season. The Rockies called up 2004 first-round pick Chris Nelson to replace Tulowitzki. Nelson was hitting .311/.384/.508 in 37 games at AAA Colorado Springs, better numbers than Tulowitzki, though obviously he was playing in AAA and in the really good hitting environment of Colorado Springs. Still, Nelson's major league equivalent (MLE) gives him a .257/.313/.404 line: not great, but it should be passable while Tulowitzki is out.

What's not entirely clear is whether or not Nelson will be starting. Nelson is a shortstop, but he's been a bit below average defensively there in minors, so most likely Clint Barmes will slide over to short and Nelson will split time with Jonathan Herrera (and maybe Melvin Mora) at second.
